The concept of the Society of the Cincinnati was that of Major GeneralHenry Knox. The first meeting of the Society was held in May 1783 at a dinner at Mount Gulian (Verplanck House) in Fishkill, New York, before the British evacuation from New York City. The meeting was chaired by Lieutenant ColonelAlexander Hamilton, and the participants agreed to stay in contact with each other after the war. Membership was generally limited to officers who had served at least three years in the Continental Army or Navy; it included officers of the French Army and Navy above certain ranks. Officers in the Continental Line who died during the War were also entitled to be recorded as members, and membership would devolve to their eldest male heir. Members of the considerably larger fighting forces comprising the Colonial Militias and Minutemen were not entitled to join the Society.

Later in the 18th century, the Society's rules adopted a system of primogeniture wherein membership was passed down to the eldest son after the death of the original member. Present-day hereditary members generally must be descended from an officer who served in the Continental Army or Navy for at least three years, from an officer who died or was killed in service, or from an officer serving at the close of the Revolution. Each officer may be represented by only one descendant at any given time, following the rules of primogeniture. (The rules of eligibility and admission are controlled by each of the 14 Constituent Societies to which members are admitted. They differ slightly in each society, and some allow more than one descendant of an eligible officer.)(The requirement for primogeniture made the society controversial in its early years, as the new states quickly did away with laws supporting primogeniture and others associated with the English feudal system.)

The Society is named after Lucius Quinctius Cincinnatus, who left his farm to accept a term as Roman Consul and served as Magister Populi (with temporary powers similar to that of a modern-era dictator). He assumed lawful dictatorial control of Rome to meet a war emergency. When the battle was won, he returned power to the Senate and went back to plowing his fields. The Society's motto reflects that ethic of selfless service: Omnia reliquit servare rempublicam ("He relinquished everything to save the Republic").[2] The Society has had three goals: "To preserve the rights so dearly won; to promote the continuing union of the states; and to assist members in need, their widows, and their orphans."

Within 12 months of the founding, a constituent Society had been organized in each of the 13 states and in France. Of about 5,500 men originally eligible for membership, 2,150 had joined within a year. King Louis XVI ordained the French Society of the Cincinnati, which was organized on July 4, 1784 (Independence Day). Up to that time, the King of France had not allowed his officers to wear any foreign decorations, but he made an exception in favor of the badge of the Cincinnati.

On June 19, 1783, the General Society of the Cincinnati adopted the bald eagle as its insigne. It is one of America's first post-revolution symbols and an important piece of American iconography. It is the second official emblem to represent America as the bald eagle, following the Great Seal of the United States. It was likely derived from the same discourse that produced the seal.

The suggestion of the bald eagle as the Cincinnati insignia was made by MajorPierre L'Enfant, a French officer who joined the American Army in 1777, served in the Corps of Engineers and later become a member of the Society. He noted, "The Bald Eagle, which is unique to this continent, and is distinguished from those of other climates by its white head and tail, appears to me to deserve attention."[9] In 1783, L'Enfant was commissioned to travel to France to have the first Eagle badges made, based on his design. (L'Enfant later planned and partially laid out the city of Washington, D.C.)

The medallions at the center of the Cincinnati American Eagle depict, on the obverse, Cincinnatus receiving his sword from the Roman Senators and, on the reverse, Cincinnatus at his plow being crowned by the figure of Pheme (personification of fame). The Society's colors, light blue and white, symbolize the fraternal bond between the United States and France.

A specially commissioned "Eagle" worn by President General George Washington was presented to Lafayette in 1824 during his grand tour of the United States. This medallion had remained in possession of the Lafayette family,[10] until sold at auction on December 11, 2007, for 5.3 million USD by Lafayette's great-great granddaughter. It was purchased by the Josée and René de Chambrun Foundation and will be displayed at Chateau La Grange, Lafayette's home 30 miles east of Paris. The medal, believed to have its original ribbon and red leather box, will be displayed in Lafayette's bedroom. It also might be displayed at Mount Vernon, Washington's former home in Virginia.[11] This was one of three eagles known to have been owned by Washington. Washington most commonly wore the "diamond eagle," a diamond-encrusted design that was given to him by the French matelots (sailors). This diamond eagle continues to be passed down to each President General of the Society of the Cincinnati as part of his induction into office.

The Cincinnati Eagle is displayed in various places of public importance, including the city center of Cincinnati, Ohio (named for the Society) at Fountain Square, alongside the U.S. flag and the city flag. The flag of the Society displays blue and white stripes and a dark blue canton (containing a circle of 14 stars around the Cincinnati Eagle to designate the thirteen colonies and France) in the upper corner next to the hoist. Refer to the section below on "The Later Society" for the city's historical connection to the Cincinnati.

During ceremonial occasions badges of society members may be worn on military and naval uniforms.[12]

When news of the foundation of the society spread, judge Aedanus Burke published several pamphlets under the pseudonym Cassius where he criticized the society as an attempt at reestablishing an hereditary nobility in the new republic.[13] The pamphlets, entitled An Address to the Freemen of South Carolina (January 1783) and Considerations on the Society or Order of Cincinnati (October 1783) sparked a general debate that included prominent names, including Thomas Jefferson[14] and John Adams.[15] The criticism voiced concern about the apparent creation of an hereditary elite; membership eligibility is inherited through primogeniture, and generally excluded enlisted men and militia officers, unless they were placed under "State Line" or "Continental Line" forces for a substantial time period, and their descendants. Benjamin Franklin was among the Society's earliest critics. He was concerned about the creation of a quasi-noble order, and of the Society's use of the eagle in its emblem, as evoking the traditions of heraldry and the English aristocracy. In a letter to his daughter Sarah Bache written on January 26, 1784, Franklin commented on the ramifications of the Cincinnati:

I only wonder that, when the united Wisdom of our Nation had, in the Articles of Confederation, manifested their Dislike of establishing Ranks of Nobility, by Authority either of the Congress or of any particular State, a Number of private persons should think proper to distinguish themselves and their Posterity, from their fellow Citizens, and form an Order of hereditary Knights, in direct Opposition to the solemnly declared Sense of their Country.[16]

"A popular election in this case is radically vicious. The ignorance of the people would put it in the power of some one set of men dispersed through the Union & acting in Concert to delude them into any appointment. He observed that such a Society of men existed in the Order of the Cincinnati. They are respectable, United, and influential. They will in fact elect the chief Magistrate in every instance, if the election be referred to the people. [Gerry's] respect for the characters composing this Society could not blind him to the danger & impropriety of throwing such a power into their hands."[17]

The debate spread to France on account of the eligibility of French veterans from the Revolutionary War. In 1785 Honoré Gabriel Riqueti, comte de Mirabeau was approached by Franklin, who was at the time stationed in Paris and suggested to him to write something about the society directed at the French public.[18] Mirabeau was provided with Burke's pamphlets and Franklin's letter to his daughter, and from this, with the help of Nicolas Chamfort, created his own enlarged version entitled Considérations sur l'Ordre de Cincinnatus which was published in London November that year, an English translation carried out by Samuel Romilly followed, of which an American edition was published in 1786.[19]

Following this public debate and criticism, George Washington, who had been unaware of the particulars of the charter when he agreed to become president of the society, began to have doubts about the benefit of the society. He had in fact considered abolishing the society on its very first general meeting 4 May 1784.[20] However, in the mean time Major L'Enfant had arrived bringing his designs of the diplomas and medals, as well as news of the success of the society in France, which made an abolishment of the society impossible. Washington instead at the meeting launched an ultimatum, that if the clauses about heredity were not abandoned, he would resign from his post as president of the society. This was accepted, and furthermore informal agreement was made not to wear the eagles in public, so as not to resemble European chivalrous orders. A new charter, the so-called Institution, was printed, which omitted among others the disputed clauses about heredity. This was sent to the local chapters for approval, and it was approved in all of them except for the chapters in New York, New Hampshire and Delaware. However, when the public furore about the society had died down, the new Institution was rescinded, and the original reintroduced, including the clauses about heredity.[21]

The French chapter, who had obtained official permission to form from the king Louis XVI of France, also abolished heredity, but never reintroduced it, and thus the last members was approved 3 February 1792, shortly before the French monarchy was disbanded.[22]

The members of the Cincinnati were among those developing many of America's first and largest cities to the west of the Appalachians, most notably Cincinnati, Ohio and Pittsburgh, Pennsylvania. The first governor of the Northwest Territory, Arthur St. Clair, was a member of the Society. He renamed a small settlement "Cincinnati" to honor the Society and to encourage settlement by Society members. Among them were Captain Jacob Piatt, who settled across the river from Cincinnati in northern Kentucky on land granted to him for his service during the War. Captain David Ziegler was the first Mayor of Cincinnati. Richard Varick was a Mayor of New York City. Lt. Ebenezer Denny (1761–1822), an original Pennsylvanian Cincinnatus, was elected the first mayor of the incorporated city of Pittsburgh in 1816. Pittsburgh developed from Fort Pitt, which had been commanded since 1777-1783 by four men who were founding members of the Society.

Today's Society supports efforts to increase public awareness and memory of the ideals and actions of the men who created the American Revolution and an understanding of American history, with an emphasis on the period from the outset of the Revolution to the War of 1812. At its headquarters at Anderson House in Washington, DC, the Society holds manuscript, portrait, and model collections pertaining to events of and military science during this period.[23] Members of the Society have contributed to endow professorships, lecture series, awards, and educational materials in relation to the United States' representative democracy.[24] The definition and acceptance of membership has remained with the constituent societies rather than with the General Society in Washington.

Over the years, membership rules have continued as first established. They provide for approving the application of a collateral heir if the direct male line dies out. Membership has been expanded in some state societies to include descendants of those who died during the war, but it remains limited.

An officer of the Continental army during the Revolutionary War can generally be represented in the Society of The Cincinnati by only one descendant at a time. The only U.S. President who was a true hereditary member was Franklin Pierce. The General Society no longer admits honorary members. Andrew Jackson and Zachary Taylor were honorary members before becoming presidents. Other presidents became honorary members while in office, and after leaving office. Each of the fourteen constituent societies has honorary members, but these men cannot designate an heir (referred to as a successor member).

The Society maintains a tradition of service in American government, especially in the federal executive branch. Members of the society have served in the Armed Forces, the State Department and other parts of the executive branch.

Today, Anderson House serves its members and the public as a headquarters, museum, and library. The Society's museum collections include portraits, armaments, and personal artifacts of Revolutionary War soldiers; commemorative objects; objects associated with the history of the Society and its members, including Society of the Cincinnati china and insignia; portraits and personal artifacts of members of the Anderson family; and artifacts related to the history of the house, including the U.S. Navy's occupation of it during World War II.

The library of the Society of the Cincinnati collects, preserves, and makes available for research printed and manuscript materials relating to the military and naval history of the eighteenth century and early nineteenth century, with a particular concentration on the people and events of the American Revolution and the War of 1812. The collection includes a variety of modern and rare materials including official military documents, contemporary accounts and discourses, manuscripts, maps, graphic arts, literature, and many works on naval art and science. In addition, the library is the home to the archives of the Society of the Cincinnati as well as a collection of material relating to Larz and Isabel Anderson. The library is open to researchers by appointment.

The Society of the Cincinnati in the State of New Hampshire owns and operates through a board of governors the American Independence Museum in Exeter, New Hampshire. The American Independence Museum is a private, not-for-profit institution whose mission is to provide a place for the study, research, education and interpretation of the American Revolution and of the role that New Hampshire, Exeter, and the Gilman family played in the founding of the new republic. Museum collections include two rare drafts of the U.S. Constitution, an original Dunlap Broadside of the United States Declaration of Independence, as well as an original Badge of Military Merit, awarded by George Washington to soldiers demonstrating extraordinary bravery. Exhibits highlight the Society of the Cincinnati, the nation’s oldest veterans’ society, and its first president, George Washington. Permanent collections include American furnishings, ceramics, silver, textiles and military ephemera. See below for a link to the museum.

Note - Every president who served in the eras of 1885 to 1923 (38 years) and from 1929 to 1953 (24 years) was an honorary member of the Society. Presidents George Washington and James Monroe were original members of the Society and President Franklin Pierce was an hereditary member.
